ESA has undertaken the development of the baseband laboratory prototype of an experimental on-board processing satellite system orientated to complement the TST/SS-TDMA prototype for a wide range of low rate services (e.g., vocoded voice, low rate circuit switched data, packet data). The current prototype investigates a few basic techniques (such as synchronization, multiservice switching) which are primarily intended for mobile systems and can be extended to further applications (e.g., enhanced VSAT's). The baseline up-link includes a flexible mixture of SCPC and very low rate TDMA and the downlink is TDM, so that compatibility with ground cellular networks could be achieved eventually. These techniques are going to be validated by a comprehensive test-bed set-up and can evolve into field experiments.

In this paper, we investigate the performance of a generic filterbank transceiver in the presence of a carrier frequency offset. We propose a theoretical model to compute the error probability in the case of a generic frequency-selective channel. Moreover, the proposed method is also extended to deal with nonuniform, i.e., wavelet, transceivers. The accuracy of the model is evaluated by means of computer simulations, using several types of filterbank transceivers. Systems based on cyclic prefix (CP) and zero padding (ZP) are considered to avoid interblock interference (IBI) in frequency-selective channels. The analytical results obtained with the proposed method allow us to quickly compare different systems, characterized by a different filterbank selectivity, as well as by different methods to combat IBI (ZP or CP).

This paper deals with a turbo multiuser detector suitable for applications in overloaded coded DS-CDMA systems. The turbo-MUD receiver is based on the use of a linear MMSE detector in the first iteration and a parallel interference cancellation scheme in the successive ones. The inputs of the interference cancellator are both the detector outputs and the soft information from a bank of turbo decoders. The performance of the proposed receiver has been derived by means of computer simulations and applications of the density evolution theory: in particular, this technique permits to properly evaluate the number of MMSE iterations, simplifying the overall receiver design.

The authors deal with an efficient high-speed packet switching fabric suitable for applications in future high speed networks. An advanced implementation architecture based on shared buffers at each input is studied. An important result is that the proposed switching fabric achieves optimum throughput-mean switching delay performance jointly with reduced buffering requirements and without having to resort to a faster switching fabric.

The definition of an integrated satellite/terrestrial mobile system is under study worldwide; an interesting approach proposed to meet the UMTS requirements is that which considers a smooth migration from current second generation systems towards future generation ones (i.e., UMTS, MBS). COST 252 Action starting from the results achieved within COST 227 Action and the related RACE II projects (e.g., MONET, SAINT and MBS) investigates the feasibility of such an evolutionary approach and contributes to the standardization phase of future generation systems.
